四季蜜龙眼产期调控技术研究

Research on maturation-controlling techniques of “Sijimi”longan

通过对四季蜜龙眼的结果母株放梢时间短截调控花期、花穗疏折修剪技术应用、不同肥水管理的试验分析,表明结果母株最佳放梢时间为3月下旬;花穗疏折修剪技术是该品种实现产期调控、丰产高效栽培的关键技术之一;合理的肥水控制措施可提高花芽分化质量及果实产量。总结四季蜜龙眼产期调控高效栽培关键技术。

By analyzing the tests on shortcutting the shooting period of fruit-bearing shoots to regulation florescence, the ap- plication of thinning and pruning technique on flower clusters, and different water and fertilizer management methods, It was showed that the last ten days of March was the optimum shooting period for fruit-bearing plants and the flower cluster thinning and pruning technique was one of the key techniques for maturation control and highly effective and high yield cultivation, and the reasonable fertihzer and water controlling measures could raise the quality of flower bud differentiation and the fruit yield. In this paper, the highly effective cultivation techniques on maturation control of ＂ Sijimi＂ longan were also summa- rized.
